Neuroimaging studies have demonstrated functional interactions between autonomic (ANS)
and brain (CNS) structures involved in higher brain functions, including attention and …

Hysteresis of the baroreflex (BR) is the result of the different BR sensitivity (BRS) when
arterial pressure (AP) rises or falls. This phenomenon has been poorly studied and almost …

In heart period (HP) variability (HPV) recordings the percentage of negative HP variations
tends to be greater than that of positive ones and this pattern is referred to as HPV …

Coronary artery bypass graft (CABG) surgery may lead to postoperative complications such
as the acute kidney dysfunction (AKD), identified as any post-intervention increase of serum …

This paper presents multi-scale fractal dimension (MFD) for the complexity assessment of
heart rate variability (HRV) and systolic blood pressure variability (SBPV) under postural …

Heart rate variability (HRV) reflects cardiac and autonomic nervous system activity. It is
usually measured over a relatively prolonged period and presented using multiple …

Purpose To detect and quantify the directional interaction changes between cardio-
respiratory system during postural change. Method Traditional frequency domain analysis …

Background: The sympathetic baroreflex (sBR) adjusts muscle sympathetic nerve activity
(MSNA) in response to arterial pressure changes but the relevance of assessing sBR control …

Both deterioration of the mechanical vascular properties of barosensitive vessels and
autonomic derangement lead to modification of baroreflex sensitivity (BRS) in coronary …

The coupling and latency between heart period (HP) and systolic arterial pressure (SAP)
variability can be investigated along the two arms of the HP-SAP closed loop, namely along …
